Geomembrane: Carbofol®

Kunststoffdichtungsbahn Carbofol®

Carbofol® HDPE geomembranes

Manufactured using high quality polyethylene resins. Carbofol® is manufactured in various thicknesses and up to 7.50m width. For sealing applications on slopes, Carbofol® is produced with an embossed structure.

Safe landfill sealing with geomembrane Carbofol

Typical solutions with Carbofol®

Hydrostatic pressure sealing system with integrated injection system - Tunnel Hirschhagen

Project advantages

  • Excellent chemical resistance due to selected raw materials
  • High interface friction angles with embossed structured surface
  • Installation advantages with up to 7.50m wide liner
  • High Melt Flow Index (MFI) allows an excellent welding performance
  • Available according to GM-13 and with BAM and DIBt approval

Selected advantages of Carbofol®

Advantage 1: Carbofol® long-term durability

Durability and high chemical resistance are ensured by carefully selected resins and a special stabilising system, which is aligned with the resin type. An enormous amount of field and lab data supports this performance.

Advantage 2: Special embossed surface structure allows a safe construction on steep slopes

New optimised BF/TF (bottom friction/top friction) embossed surface structure has been developed to increase shear strength towards typical shearing partners.

Advantage 3: Carbofol® HDPE liner comes with weld protection stripes and lateral marking

The Carbofol® geomembranes are provided with a white edge mark on both sides. These edge marks indicate the recommended areas of overlapping and are a visual aid during the installation. Furthermore, a thin protective sheet (~150mm wide) is attached to both edges and is peeled off immediately prior to the welding process to provide an absolutely clean welding area.

Advantage 4: HDPE Geomembrane with high Melt Flow Rate (MFR)

Carbofol® HDPE geomembranes feature a Melt Flow Rate (MFR) between 1 and 3g/10 minutes tested at 190°C/5kg and thus have the advantage of a large welding window. This makes Carbofol® geomembranes flexible and easy to handle during on-site installation. The speed at which welding processes can be carried out on Carbofol® geomembranes is distinctly higher than that of other liners with an MFR less than 1g/10min. This gives Carbofol® yet another major benefit during on-site installation and welding.
